T1 PNP PRO / T1 VTOL / F01 FX-25A BLS ESC

Recommended to calibrate the ESC throttle range before first use.

 

Turn on the radio/transmitter, push the throttle stick to max > power on the ESC > when you hear "Di" from the ESC > pull the throttle stick to min > the ESC will then emit "Di Di" as confirmation of calibration done.
